Application filed February 9, 1923. Serial No. 617,972.

To all whom it may concern:

Be it known that. BENJAMIN F. LINDSLEY, a citizen of the United StatesofAmerica, residing atMansfield, in the county of Rich: landand'State of Ohio, has invented cer-. tain new and useful IIHPITOVGIIIGIItSilII Bed: springs, of whichthefollowing is a specification." i

Ihe -present invention consists of improve-. ments in the structure describedand claimed inzPatent N 0. 812,939, hearing. date of Feb ruary 20, 1906, and entitled bedspring, whereby the old objects are retained and new objects attained in combination there-. with asherein particularly referred to.

One of thehobjects of the invention consists in mounting and supportinga series of conicalcoiled springs on suspendedbars in such a manner'as to permitthe-mounting of said springs. substantially throughout the entire area of the; bed spring as a whole, so as to provide yielding or resilient means to; support the body of the userof the; bed spring at all points, which result is accomplished in the presentinvention by the method: ofjattachingcthe suspension; bars to the .risers and; connections of, the frame.

1r Further objects 'areto provide, means of preventing a' direct pull being exerted on the serieslof zconic'al springs .to. prevent them from-being drawn inirregular or uniform positions, when pressure is being exerted on the-side, as for'instance in the event a person sitting on the .side of the bed, and to provide..means. of attaching and .vremovably locking the coiled springs .to' the. bars. upon whichthey are mounted.-

Further objects, ,.of ,.,the invention are to provide means for bracing the entire spring bed structure at or about the center portion thereof,.-through the medium of, a brace suspended from the side bars oft-he frame,

and to construct the spring frame. .soas to permit the attachment of. the side bars of the frame in. a position to be directly over the.

sidelrailsl-of the bed spring'and bed frame. These". and other .objects are attained by thexconstructionyof a bed spring illustrated in: the accompanyingv drawings in which Fig' ure; 1 is'a planvview of the bed sprin showing the bed spring assembled.

As stated in the objects set out herein, the present invention consists in retaining the results obtained in the :patent identified herein, in combination with new resultsby reconstructing, assembling and combining the :original elements of the patent herein identified withothersin such a wayxas to obtain new results and more eflicientires sults than obtained, by the structure shown Eng described/in the. patent herein; identi- In the construction of a bed spring to obtain the newresults set, out in the objects asgherein set forth, risers 1 are provided, which areformed to curvequpwardlyyrear wardly and inwardly thereby forming rounded corners on the bed springuwhen the same is assembled. The risers'are pro vided with inwardly projecting lugs 2 and The lugs 2. and 3 are positionedonthe risers adjacent to the top and bottom.there-. of in spaced relation to each other.

Attention is called to the fact that the; risers are formed in rights and lefts; The top portions vof therisers projectinwardly in opposed relation and in alinement with. each other. Side rails 4 and 5 preferably made tubular in cross section, are secured to the bosses 6 of the risers. Endbars 7 and8,

preferably made angular in cross section,

spacedv relation to the angle bars 7and -8,

. and-at difierent horizontal planes.

The construction of the bed spring so far describes the frame consisting of duplicate right and left risers positioned to form the corners of the bed spring frame, having end bars secured thereto in spaced relation to each other by bolts 9 or the like. The construction described comprises the stationary frame of the bed spring. A series of supporting bars 11 are yicldingly suspended from the auxiliary bars 10, by a ser'es of coiled springs 12, which are attached to the ends of the bars 11 and to the auxiliary bars 10. i

A series of conical springs 13 having their ends 14 at the small portion of the cone turned (as shown at 14-) are mounted upon and fitted to apertures formed in the supporting bars 11. The. turned portion provides means of locking the conical springs to the supporting oars 11 as shown in Figure 4;. The upper portion of the conical springs 15 are connected together sidewise by short links of chain 16. Chainsli' are interposed between the series of conical springs and cross the short links 16 at right angles and are connected thereto. 7

A series of expansible springs 18 are connected to the end angle bars 8 at one end and the opposite end is connected to tie plates 19. Chains 20 and 21 are connected to the tie plates one end and their opposite ends are connected to links 22 which are in turn connected to the end series of conical springs 13. i p

The construct'onas described provides a chain top which yields with the conical springs to permit a downward and horizontal yielding "movement simultaneously. The expansible springs 18 and 12 yield in a horiontal direction and the conical springs in a vertical direction, thereby providing a bed spring that conforms and yields to every irregular movement of the body of the user,

irrespective of the position of the bodyof links the user upon the bed spring. r

In order to 'l'l'lflllltilln and hold the series of springs in uniform position and at the same time permit yielding movem'ent of all of the springs and automatically maintain and return the springs to their normalrelation with respect to each other, side bars 23 and 24s are provided and connected by expansible springs 25 and. 26 to the lugs 3 of the risers.

- Continuous chains 27 and 28 are interposed between the side bars and-tlie'side series of conical springs and are yieldingly connected through the medium of the plates 19 and expansible springs 18 to the. end bars 8.

The continuous chains 27 and 28 are connectedto conical springs at the top thereof The continuous chain 27-;and 28 are also connected to the side bars-23 and 241-. through the medium of the 30 between each series of: conical springs. It ,will be noted that ,yieldingly side bars 23 and 2e are not connected directly to the conical springs; therefore when pressure is exerted upon the side of the bed as for instance when the user sits on the side thereof a direct pull is not exerted on the top of the coil springs but indirectly through the mediunrof the yielding chains 27 and 28; thereby preventing the springs from being excessively pulled, stressed, or moved from their vertical positions.

I t will be observed that this construction serves to maintain the entire series of conical springs in uniform position and regular with respect to each other, and provide means to automatically return the springs to normal position when the pressure is released upon any part of the areaof the top of the bed spring.

To maintain the series of supporting bars 11 in uniform spaced relation to each other and at the same time tend to support, same from the side bars, a brace 31 is provided to which the supporting bars 11 are attached. The brace 31 is secured to the supporting bars 11 and is suspended from the side bars 23 and 261- by theinelined members 32 and 33 which are attached to the side bars 23 and 2 1 at one end and to the brace 31 at the other end as shown in Figure 3.

The brace provides means of strengthening the" center of the bedsp'ring,maintains the supporting bars 11 inuniform relation to each other, holds the side bars in proper relation to each other and tends to maintain the entire area of the'top of the bed spring in normal position.

Attention is calledto the fact that the members 32 and 33 are preferably attached toward the center of the brace bar 31. This method of connecting the supporting memhers to the brace bar '31 serves also to maintain the conical springs in uniform and normal positions whether subject to pressure or not. i Angular plates 34 as shown in- Figure 8 are used to connect the continuous chains and springs at the sides of the bed spring. '6 Reference numeral 35 refers to "lugs formed integral. with the risers to prevent sidewise or lateral movementof the bed spring; i I claim: 7 i In a bed spring,'risers extending rear wardly from the body portions thereof, thence inwardly at the top, angle end bars, means to secure a pair ofangle end bars to said risers in spaced apart'relation verti-. cally and longitudinally from each'other, supporting bars yieldingly connected to one of each pair of the angle end bars,.a plurality of conical springs removably mounted on said supporting bars, a series ofchains connecting the top portions of said conical springs, wherebythe top portion of the springs and chains provide; the top;0f.1the
